Firstly I think devs are battling a mix of new short term content and new long term content. They only have so many programmers and to give big new events each week would likely take up their time. Even smallish changes like whole clan event could take a while to program, test, and put out. Hopefully copy and pasted events means devs are focusing their efforts on bigger and better content that will improve KAW long term. No matter what done they will upset players. If they focused mostly on events then we wouldn't be happy they are ignoring bugs and new major content. If they focus on bugs and content instead of events people complain about the events being similar. We will see where the future takes us.
To be completely honest, while the artwork is cool and storyline could capture you for a moment idc whether I'm collecting stuff from hyndemara or shmyndemara. I play for reasons other than events they are just a fleeting focus to grow. TL;DR copy and paste events are fine, events aren't even a big deal besides getting your rewards
My thoughts are Why do you care? Why don't you have something better to do with your time ? Why is it so upsetting to you ? Work smarter, not harder.
I'd love to hear new and original ideas from the complainers as to what these new and original events are to be please...it is a tap game, not sure what you are looking for in terms or originality withn the framework of the game...please share!
